A very simple circularly polarised (CP) printed patch antenna with enhanced bandwidth has been designed, fabricated and tested. The antenna consists of two semi‐circular patches and a rectangular ground plane, and is excited by a simple microstrip feedline. The total substrate size is 50 × 50 × 1.52 mm 3 . The measured −10 dB impedance bandwidth is 101% (2.84–8.7 GHz) and the measured 3 dB axial‐ratio (AR) bandwidth is 49.8% (3.95–6.57 GHz). Good agreement is achieved between measured and simulated results.
